AMD announced "Zen 4" with Ryzen 7000 series, RDNA3 teased

Gief Zen4 with 3D V-Cache! Can't wait to see benchmarks early 2023.

So AMD is not doing big and little cores, like Intel does?

Intel does big/little because they are unable to deliver cores with little power consumption. AMD with 5nm should be capable to use less power.
It's only me or the prices are high. My ryzen 1600x cost much less when I bought.
Well... I'll wait for am6 or risc-v.

Min 6 cores? Isn't there an entry model or something?

Rumors has it that they might do a big/little with a zen4/zen5 combo. But then as stated earlier, Zen are so efficient that they do not need it.

Remember that the effecient cores are just rebranded Atom-style cores. Nothing impressive and are just plain better to avoid if possible.

6 cores is entry model… They do 6 cores and 8 cores since more than a decade (here, the linked models are from 2011).

What is more problematic is that a 6 core CPU from AMD like the FX-6100 was costing $165 at introduction with 95W TDP while now the Ryzen 5 7600X is $299 with 105W. They can definitely produce some more-entry-level CPUs (probably released later?), they just have no reason to make them having less than 6 cores.

If I'm right even the 6 core FX-6100 from 2011 was in fact produced with 8 cores with 2 being disabled… Producing a CPU with less than 6 cores in 2022 is probably requiring a specific production process that would skyrocket their price for no benefit… the less costly solution to produce CPUs with less than 6 cores in 2022 is probably to produce the cores and to disable them. Better keep them enabled if they work.

I can get a CPU good enough for many things for 50 Euros from Intel, 2 cores, released in 2022 ("G6900T").
I'd buy such a thing e.g. for my HTPC if the last one gives up.
Dunno why AMD shouldn't be able to make something similar.

Will these ones contain the Pluton backdoor?

The Ryzen 5 7600X is the entry level model for the mainstream range of products. You don't compare the same range of products. 1. this is Ryzen, 2. this is Ryzen 5, it is expected to be good for gaming.

The G6900T is a Celeron for light clients, point of sales and tablets, on AMD side you may want to look for lower-end Ryzen 3 or Athlon. Even the Ryzen 3 range (“entry level” Ryzen range) may still be too high level for what your are looking for as they are still Ryzen CPUs (Ryzen is not the entry level family).

Dunno why AMD shouldn't be able to make something similar.

Of course they do something similar, they even have more low-level CPU families. What's right is that they are harder to find as a consumer outside of OEM, I would agree on that and maybe in the end you will buy Intel because of that, who knows…

I just picked some AMD CPUs (not all are listed there unfortunately) for a comparison:
https://www.cpubenchmark.net/compare//4605vs4924vs4927vs4389

AMD has released a 2 core Ryzen 3 5125C in May 2022 but is not listed by cpubenchmark.net yet but you may look at the 4 core 5300GE and remind it has twice the cores but is from more than one years ago so you should get something between the Athlon Gold 3150C and the Ryzen 3 5300GE, but with less energy consumption than the Celeron for sure.

Producing 2 cores Ryzen 5 doesn't make sense for AMD, that's for other ranges of products (and they exist).

I can't say for sure, but I haven't seen or heard a single AMD rep state that Ryzen 7000 is infected with Pluton, be it at an event or investor meeting, so I'm hopeful.

Avoiding due to pluton.

I think it's cool, but support until 2025... That seems a little short. Is it?

I mean most won't get these until 2023, and maybe I'm weird, but I don't buy hardware with the intent to replace it in just a few years.

It should mean that they will bring new processors for the platform in 2025 - not that you cannot use your old processor anymore after 2025. I cannot think of a case where I replaced a processor, but not mainboard, RAM, ...

CPUs look promising, but I wonder with 170 W TDP vs current gen 105 W, will high end coolers be able to handle it on full load?

Also, how do you apply thermal paste on that heat spreader plate? I.e. won't it go into those openings?

Yes I think it is short... but IMHO, I think AMD will extend it beyond 2025, but they dont want to piss off their customers if all of their boards do not support all of the latest features. (Like what happened when some of the AM4 boards did not work at m.2 4.0 speeds) No idea how much further beyond 2025 though..

What is Pluton?

Something you don't want on your computer, depending on where you sit regarding user freedom.

In simple terms, it's a DRM chip inside the CPU that Microsoft & AMD designed that is similar to those found in the modern Xbox and has the potential to reign complete control over your computer and is cloud connected. For example it can submit documents to the cloud for "attestation" and "verify" that the OS isn't tampered or running pirated software. It can also receive updates from Microsoft via Windows Update and you have absolutely no control over it or say in what it may or may not do. It's great for companies like Epic and their EAC though who wish to have more control over you and your games, it's a wet dream for them.

Sadly, not all details are known about it as Microsoft are keeping their cards close to their chest regarding the full details of how it works.

The more worrying thing isn't so much the potential of "what can it do" but rather why are certain manufacturers, such as Dell & Lenovo rejecting it? They are claiming they will ship it disabled and inactive. So you have to ask yourself why would they, being companies that are fully in the pocket of Microsoft, chose to go against Microsoft like that? What do they know?

Sadly, I am biased against it as I do not support it so I am probably not the best person to explain it. I want gaming to be successful on Linux, but not at the cost of compromising my freedom to use my computer as I wish or to give up my privacy. I simply can't support such a technology.

Probably wait until V-Cache. Also not sold on RDNA3, probably good for pure rasterization work but I suspect no matter how much work they put into RayTracing backend, it never going to work well, especially under Linux.

Twice in recent memory, with current AM4... 1800/3700/5800.
Multiple times more in ancient history, which many of you may not remember, or weren't even born. I remember several generations of 3- and 486es, and a couple of Athlons, all running fine in the same main boards as their predecessors, and often more than one upgrade. I have always been assembling my machines myself, and I have always hated when I had to upgrade the main boards... and still do.

As such, I agree, "until" 2025 is rather short. If you read it critically, that covers two years. Barely enough for one end-of-life upgrade.
